Re: Uh oh (diet for healthy bones)

[Guest guest]

Rodney,

Below are a couple of links about nutrition for the bones. You are

right that you need to supply the raw materials to help your body

heal.

Bones consist of a collagen matrix with hydroxy apatite crystals (a

calcium phosphate mineral). Apatite contains not only calcium and

phosphorous; it also contains fluorine. This is why fluoride

treatment strengthens developing teeth. Magnesium also influences the

growth of the apatite crystals. Extra protein will assure that the

aminoacids needed to build the collagen matrix are present. Gelatin is

basically collagen that has been boiled for a long time.

The right nutrition would include calcium, magnesium, protein, Vitamin

D (mmhh... It seems that you need to consume milk and dairy products

and get some sunshine!).

Bone Health and Osteoporosis: A Report of the Surgeon General

Chapter 6: Determinants of Bone Health

The Institute of Medicine recently considered other bone-related

nutrients, including phosphorus, magnesium, and fluoride (IOM 1997).

Phosphates make up more than half the mass of bone mineral. About 85

percent of the body's phosphorus and 60 percent of the body's

magnesium are found in the skeleton. Both phosphorus deficiency and

excess have been considered as having adverse effects on bone health

(Heaney 2004), but both can be avoided with a healthy diet. Magnesium

may enhance bone quality by influencing growth of crystals of

hydroxyapatite, the mineral compound found in bone. Fluoride is known

to reduce cavities in teeth, a hard tissue that is similar to bone,

but its role in maintaining skeletal health is less clear (IOM 1997).

Other nutrients/dietary components that appear to play a positive role

in bone health include vitamin K, vitamin C, copper, manganese, zinc,

and iron. These micronutrients are essential to the function of

enzymes and local regulators and therefore are important to forming

the optimal bone matrix.

Dietary protein deficiency induces osteoporosis in aged male rats.

Bourrin S, Toromanoff A, Ammann P, Bonjour JP, Rizzoli R.

Department of Internal Medicine, University Hospital, Geneva,

Switzerland.

Low dietary intake is common in elderly males with low femoral

neck areal bone mineral density (BMD). To evaluate the selective

influence of a low-protein diet in the pathogenesis of osteoporosis in

males and to uncover early and late adaptation of bone cells to

protein deficiency, 8-month-old male rats were pair-fed a control (15%

casein) or isocaloric low-protein (2.5% casein) diet for 1 or 7

months. BMD, bone ultimate strength, stiffness, and absorbed energy

were measured in tibia proximal metaphysis and diaphysis. After

double-labeling, histomorphometric analysis was performed at the same

sites. Serum osteocalcin, insulin-like growth factor I (IGF-I), and

urinary deoxypyridinoline excretion were measured. In proximal tibia,

isocaloric low-protein diet significantly decreases BMD (12%),

cancellous bone mass (71%), and trabecular thickness (Tb.Th; 30%),

resulting in a significant reduction in ultimate strength (27%). In

cortical middiaphysis, a low-protein diet decreases BMD (9%) and

enlarges the medullary cavity (36%), leading to cortical thinning and

lower mechanical strength (20%). In cancellous bone, protein

deficiency transiently depresses the bone formation rate (BFR; 60%),

osteoid seam thickness (15%), and mineral apposition rate (MAR; 20%),

indicating a decrease in osteoblast recruitment and activity. Cortical

loss (15%) results from an imbalance between endosteal modeling drifts

with impaired BFR (70%). From the first week of protein deficiency,

osteocalcin and IGF-I levels drop significantly. Bone resorption

activity and urinary deoxypyridinoline remain unchanged throughout the

experiment. Protein deficiency in aged male rats induces cortical and

trabecular thinning, and decreases bone strength, in association with

a remodeling imbalance with a bone formation impairment and a decrease

in IGF-I levels.

Hi folks:

I much appreciate the input I have gotten here lately, both on and

off list. All of it helpful and constructive.

I have been struck by my inability to find anywhere any nutrition

suggestions for people with broken bones. So I have upped my Ca + D

and protein intake (I understand that no one ever suffers a P

deficiency). But perhaps it doesn't matter.

OTOH perhaps the failure of some fractures to mend may be because of

insufficient attention being paid to making sure the body has an

adequate supply of raw materials?

Those are EXCELLENT links on bone. Many thanks, Tony. We should

probably all read them, especially the one from the Surgeon-General.

FTR I skipped over a six inch snow-covered obstacle BECAUSE!!! I was

afraid I might trip if there was something in it under the snow.

When I landed the other side on my right foot, it turned out to be

sheer ice and my right foot slid rapidly left. I didn't have the time

(or the wits?) to think about employing appendages.

Incidentally, after checking various sites regarding my prescribed

pain killer, I have decided it may be preferable to put up with the

pain instead.

Hi folks:

Made my first trip to see the bone man today. (Previous trip was to

emergency department).

Nutrition advice ............... " eat your regular diet " . fwiw.
